Application

Developed for use in immunohistology and immunoblotting as a precipitating substrate for the localization of peroxidase activity. DAB is the immunohistology substrate of choice as it produces an intense brown-black stain which is resistant to alcohol. Slides stained with DAB may be dehydrated, mounted in resinous media, and stored for future reference. SIGMAFAST DAB Tablets require no additional buffers or steps to prepare an active substrate solution. Tablets are individually packaged in foil packets

Preparation Note

Each tablet set dissolved in 15 mL deionized water yields a ready-to-use buffered solution containing DAB and urea hydrogen peroxide.

Zebra finches (Taeniopygia guttata) are sexually dimorphic songbirds, not only in appearance but also in vocal production: while males produce both calls and songs, females only produce calls. This dimorphism provides a means to contrast the auditory perception of vocalizations

In the mammalian brain, adult hippocampal neurogenesis (AHN) is suppressed by chronic stress, primarily at the ventral pole of the hippocampus. Based upon anatomy, we hypothesise that the caudal pole of the avian Hippocampal Formation (HF) presents a homologous subregion.

Polyglutamine expansion in proteins can cause selective neurodegeneration, although the mechanisms are not fully understood.
